Depending on the condition of the power supply, unstable power or voltage may cause malfunction of the parts or control system. (At the ship or places using power supply from the electric generator, etc.). HEATING SYSTEM FILLING Set the pressure of the heating circuit in the expansion vessel to 1.5 bar. Usually, the replenishment of the heating circuit is stationary and pre-connected to the water inlet, in which case the replenishment takes place individually according to the system.
CAUTION Do not install the Air to Water Heat Pump in the following places. The place where there is mineral oil or arsenic acid. There is a chance that parts may get damaged due to burned resin. • The capacity of the heat exchanger may be reduced or the Air to Water Heat pump may be out of order. The place where corrosive gas such as sulfurous acid gas generates from the vent pipe or air outlet.
Safe parts are the ones with which the worker can work in a flammable atmosphere. Other parts may result in • ignition due to leakage. Replace components only with parts specified by Iglu tech. Other parts may result in the ignition of refrigerant in • the atmosphere from a leak.
LEAKAGE DETECTION METHODS The leakage detector shall be calibrated in a refrigerant-free area. Make sure that the detector is not a potential source of ignition. The leakage detector shall be set to the LFL (lower flammability limit). ...
There must be no aggressive chemicals in the environment. Indoor units should not be installed close to walls; the front of the unit should always be accessible. A drainage system must be provided in the room where the unit is installed. In this case, leaking water can be drained.
WHEN INSTALLING MORE THAN ONE OUTDOOR UNIT The units must be installed according to distances declared, to permit accessibility from each side, either to guarantee the correct operation of maintenance or repair products. The unit’s parts must be reachable and removable completely under safety conditions (for people or things).
